The ratio of boys to girls in the seventh grade at GACA is 2 to 4 if there were 850 kids in the seventh grade how many would you expect to be girls round to the nearest whole number?
The ratio of boys to girls is 2 to 4, which can also be written as 1 to 2.
Let's denote the number of boys as B and the number of girls as G. Therefore, we have the following equation:
B/G = 1/2
Now, we know that the total number of students is 850, so we can write another equation:
B + G = 850
To solve this system of equations, we can use substitution. Rearranging the first equation, we get B = G/2. Substituting this into the second equation, we have:
G/2 + G = 850
Multiplying through by 2 to clear the fraction, we have:
G + 2G = 1700
Combining like terms, we get 3G = 1700
Dividing both sides by 3, we find G = 1700/3 = 566.6667
Since we cannot have a fraction of a student, we round this value to the nearest whole number, which is 567.
Therefore, you would expect there to be 567 girls in the seventh grade at GACA.
